Police responded to a domestic disturbance 911 call where "the caller advised that her son was threatening the family with a knife." Police responded to 902-B Webster Avenue shortly after 5 p.m. and found Webb carrying two butcher knives.

Police officials said Webb refused to drop the knives and "aggressively advanced" toward officers, who then fired at Webb.

HEMSI paramedics were on the scene, but Webb was pronounced dead upon arrival to Huntsville Hospital.

An internal review will take place.

Anytime an internal review is conducted, facts are presented by the internal affairs department to a shooting review board, consisting of members of the district attorney's office, Huntsville police officers, city attorneys and members of the training staff, said Huntsville police Sgt. Mark Roberts.

Based on the decision of the review board, the district attorney's office will decide whether to present the case to a grand jury.
